This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Full-Stack Software Engineer (Frontend & Mobile Focus) based in France.
This is an exciting opportunity to join an innovative engineering team developing AI-powered technology that improves operating room workflows and supports better patient care. In this remote-first role, you will combine deep frontend expertise with full-stack engineering contributions to build reliable, intuitive applications used by clinical teams in high-stakes healthcare environments. You will take ownership of frontend architecture, design systems, and mobile-ready experiences while helping establish engineering standards across the team. Working closely with designers, product specialists, and machine learning engineers, you will deliver impactful features from concept through deployment. The role also offers opportunities to mentor colleagues, influence technical direction, and collaborate directly with clinical users through occasional international travel.
Shape frontend strategy and architecture: Define and evolve frontend standards, architecture, and development practices to support rapid iteration, maintainability, reliability, and compatibility across a wide range of devices.
Develop high-quality applications: Build and maintain responsive, scalable frontend experiences using React and TypeScript, while contributing across the full technology stack when needed.
Build and maintain design systems: Collaborate closely with the design team to implement a consistent design system that supports usability, visual quality, and efficient product development.
Improve frontend modularity and mobile readiness: Refactor and modularize frontend code to improve testability, maintainability, and support for mobile experiences.
Promote engineering best practices: Mentor and guide fellow engineers in frontend development standards, code quality, testing, and architectural patterns, enabling effective contributions across the engineering team.
Deliver continuous improvements: Ship regular product enhancements and fixes, maintaining high standards of quality and minimizing regressions.
Own projects end-to-end: Take responsibility for technical initiatives from research, design, and prototyping through implementation, testing, and deployment, collaborating across product and machine learning teams.
Contribute to product development: Provide structured feedback, prototype solutions, test new functionality, and identify opportunities to improve the user experience and product capabilities.
Work across the technology stack: Contribute to systems involving React, TypeScript, Elixir, Phoenix, C++, Google Cloud Platform, GitHub Actions, NixOS, PostgreSQL, ETL pipelines, GraphQL, REST APIs, and healthcare integrations such as HL7 and FHIR.
Collaborate with clinical users: Participate in occasional international travel to hospitals to observe real-world workflows, understand clinical needs, and co-design solutions with healthcare professionals.
Take ownership of reliability: Proactively identify and resolve technical issues, anticipate edge cases, communicate challenges, and deliver dependable software for critical healthcare environments.
Strong experience architecting and developing highly maintainable, reliable web applications that work seamlessly across devices.
Extensive frontend engineering expertise, particularly with React and TypeScript, and a strong understanding of modern frontend architecture and development practices.
Experience building, maintaining, or evolving design systems and reusable frontend components.
Mobile development experience or a strong understanding of mobile-ready frontend architecture and responsive application design.
Full-stack engineering knowledge and an interest in contributing across frontend, backend, infrastructure, and data systems.
Familiarity with technologies such as Elixir, Phoenix, C++, Google Cloud Platform, GitHub Actions, NixOS, PostgreSQL, ETL pipelines, GraphQL, REST APIs, or healthcare interoperability standards such as HL7 and FHIR is advantageous. Deep experience with every technology is not required.
Strong software engineering fundamentals, with a focus on clean, reliable, testable code and minimizing regressions.
Ability to think systematically, anticipate edge cases, and balance technical rigor with pragmatic, fast execution.
Experience collaborating with designers and translating design concepts into effective, user-friendly software.
Strong communication and collaboration skills, including the ability to provide constructive feedback, share knowledge, and mentor other engineers.
A proactive, ownership-driven mindset, with the confidence to identify problems, take initiative, and raise issues when needed.
Adaptability and curiosity, with the motivation to learn new technologies and contribute beyond your primary area of expertise.
Comfort working in a remote-first, collaborative environment that values candid communication, mutual respect, and continuous learning.
Interest in developing technology that addresses meaningful real-world challenges, particularly in healthcare.
Willingness to undertake occasional international travel to visit hospitals and collaborate with clinical users.
